Opportunities & Challenges

What is at stake?

Agriculture has much to lose in a world where climate change goes unmitigated. Future conditions will fundamentally challenge the resilience of our food and farming systems. However, climate change also presents unique opportunities for agriculture to become a leader in addressing climate change.

As a land-based system dependent on weather and natural resources, agriculture is uniquely vulnerable to the predicted changes in climate. Agriculture is also exceptionally positioned to assist with climate change mitigation through on-farm conservation practices that reduce greenhouse gas (GHG) emissions and sequester CO2. Many of the practices modeled by sustainable and organic farming practitioners offer some of the best strategies for reducing agriculture’s carbon footprint, mitigating climate change, and helping farmers to adapt. However, to date, the sustainable agriculture perspective has been largely absent from the climate change policy debates.

What is the impact of agriculture on the climate?

Approximately 13 percent of all global CO2 emissions come from agricultural practices, according to the Intergovernmental Panel on Climate Change. Fertilizer applications account for most of the world’s nitrous oxide emissions (298 times more potent than CO2), and agriculture contributes two-thirds of all methane emissions (25 times more potent than CO2). When accounting for agriculture-related activities—manufacturing chemical inputs, transporting water, and the processing, packaging, and transportation of food—agriculture’s contribution to GHG emissions increases.

What is the impact of climate change on agriculture?

Agriculture faces potentially profound impacts from climate change. According to the UN Intergovernmental Panel on Climate Change, predicted climate change impacts for the west include drier conditions with more frequent and prolonged heat waves, reduced water resources and increased pest and disease pressures. What solutions does sustainable agriculture offer? The vision for agriculture’s future that has long been articulated and modeled by sustainable agriculture provides powerful solutions to the climate crisis. These include practices and policies that minimize nitrogen-based fertilizer use, decrease tillage, increase biodiversity, conserve water, protect  farmland, produce on-farm renewable energy, and build the organic content of soil to sequester more carbon—all of which mitigate climate change. Many of these solutions also help prepare farmers to adapt to the coming challenges of climate change. In addition, addressing climate change in the agricultural sector has many important co-benefits, including:

  • Energy and water conservation
  • Improved air and water quality
  • Reduced use of petrochemicals
  • Increasing biodiversity
  • Improved farm worker and public health
  • Diversified farmer incomes through payments for eco-system benefits

What is the role of CalCAN?

The California Climate and Agriculture Network (CalCAN) brings a sustainable agricultural perspective to climate change and agriculture policy. Our efforts are aimed at increasing funding for research, technical assistance and financial incentives for farmers whose practices reduce GHG emissions, sequester carbon, and provide many environmental co-benefits. Moreover, we aim to build capacity among sustainable agriculture advocacy organizations and our farmer members to engage in climate change debate. CalCAN represents sustainable agriculture organizations and allied groups that work directly with California’s sustainable and organic farmers.

“Human well-being is wrapped up with how food is produced. Ingenious systems were developed over the past century to supply food, with remarkable reliability, to a good portion of the world\'s 6.7 billion people. But these systems need a fundamental restructuring over the next few decades to establish sustainable food systems that both slow and are resilient to climate change.”
